6Language Interoperability

Using the conversion rules in Libraries and Collections, and R6RS library
can refer to modules that are implemented in other dialects supported
by Racket, and other Racket modules can refer to libraries
that are implemented in R6RS.

Beware that a pair in R6RS corresponds to a
mutable pair in racket/base. Otherwise,
R6RS libraries and racket/base share the same
datatype for numbers, characters, strings, bytevectors (a.k.a. byte
strings), vectors, and so on. Hash tables are different. Input and
output ports from racket/base can be used directly as
binary ports with R6RS libraries, and all R6RS ports can be used
as ports in racket/base programs, but only textual
ports created via R6RS libraries can be used by other R6RS
operations that expect textual ports.
